Slide 11: Follicular Adenoma of Thyroid
|
The tissue on your
slide is actually only a small wedge out of the intact and much larger lesion.
You should be able to find part of the capsule and see the difference between
the cells within the capsule and those outside. Yes you will see many inflammatory
cells. The chronic inflammation seems to be a fairly consistent part
of many forms of thyroid disease.
See this slide with the
virtual microscope. |

In this picture you
see a wedge of the adenoma with the capsule compressing the surrounding normal
thyroid tissue. There will very likely be a few chronic inflammatory cells
with some fibrosis around the adenoma, and elsewhere in this slide. How do
we distinguish an adenoma from a malignant lesion in
the thyroid
? What features tell us this is benign? Does it have any malignant potential? |
